When there is interference, it may be reduced or
eliminated by taking the following measures:
1. Clean door and sealing surface of the oven.
2. Reorient the receiving antenna of radio or
television.
3. Relocate the microwave oven with respect to
the receiver.

This appliance must be grounded. This oven is
equipped with a cord having a grounding wire
with a grounding plug. It must be plugged into
a wall receptacle that is properly installed and

3
grounded. In the event of an electrical short
circuit, grounding reduces risk of electric shock
by providing an escape wire for the electric
current. It is recommended that a separate
circuit serving only the oven be provided. Using
a high voltage is dangerous and may result in a
fire or other accident, causing oven damage.
WARNING: Improper use of the grounding
plug can result in a risk of electric shock.
Note:
1. If you have any questions about the
grounding or electrical instructions,
consult a qualified electrician or service
person.
2. Neither the manufacturer nor the dealer
can accept any liability for damage to the
oven or personal injury resulting from
failure to observe the electrical connection
procedures.
The wires in this cable main are colored in
accordance with the following code:
Green and Yellow = EARTH
Blue = NEUTRAL

3. Arrange food carefully. Place thickest
areas towards outside of dish.
4. Watch cooking time. Cook for the shortest
amount of time indicated and add more as
needed. Food severely overcooked can
smoke or ignite.
5. Cover foods while cooking. Covers prevent
spattering and help foods to cook evenly.
6. Turn foods over once during microwaving
to speed cooking of such foods as chicken
and hamburgers. Large items like roasts
must be turned over at least once.
7. Rearrange foods such as meatballs
halfway through cooking both from top to
bottom and from the center of the dish to
the outside.

If the oven fails to operate:
1. Check to ensure that the oven is plugged in
securely. If it is not, remove the plug from
the outlet, wait 10 seconds, and plug it in
again securely.
2. Check for a blown circuit fuse or a tripped
main circuit breaker. If these seem to be
operating properly, test the outlet with
another appliance.
3. Check to ensure that the control panel is
programmed correctly and the timer is set.
4. Check to ensure that the door is securely
closed engaging the door safety lock system.
Otherwise, the microwave energy will not
flow into the oven.
IF NONE OF THE ABOVE RECTIFIES THE SITUATION, THEN CONTACT A QUALIFIED TECHNICIAN. DO
NOT TRY TO ADJUST OR REPAIR THE OVEN YOURSELF.

1. The ideal material for a microwave utensil
is transparent to microwave, it allows
energy to pass through the container and
heat the food.

2. Microwave can not penetrate metal, so
metal utensils or dishes with metallic trim
should not be used.
3. Do not use recycled paper products when
microwave cooking, as they may contain
small metal fragments which may cause
sparks and/or fires.
4. Round /oval dishes rather than
square/oblong ones are recommended, as
food in corners tends to overcook.
5. Narrow strips of aluminum foil may be
used to prevent overcooking of exposed
areas. But be careful, don’t use too much
and keep a distance of 2.54cm between
foil and cavity.
The list below is a general guide to help you select the correct utensils.

1. Turn off the oven and remove the power
plug from the wall socket before cleaning.
2. Keep the inside of the oven clean. When
food splatters or spilled liquids adhere to
oven walls, wipe with a damp cloth. Mild
detergent may be used if the oven gets
very dirty. Avoid the use of spray and
other harsh cleaners as they may stain,
streak or dull the door surface.
3. The outside surfaces should be cleaned
with a damp cloth. To prevent damage to
the operating parts inside the oven, water
should not be allowed to seep into the
ventilation openings.
4. Wipe both sides of the door and window,
the door seals and adjacent parts
frequently with a damp cloth to remove
any spills or spatters. Do not use abrasive
cleaner.
5. Do not allow the control panel to become
wet. Clean with a soft, damp cloth. When
cleaning the control panel, leave oven
door open to prevent oven from
accidentally turning on.
6. If steam accumulates inside or around the
outside of the oven door, wipe with a soft
cloth. This may occur when the
microwave oven is operated under high
humidity condition. And it is normal.
7. It is occasionally necessary to remove the
glass tray for cleaning. Wash the tray in
warm sudsy water or in a dishwasher.

11
8. The roller ring and oven floor should be
cleaned regularly to avoid excessive noise.
Simply wipe the bottom surface of the
oven with mild detergent. The roller ring
may be washed in mild sudsy water or
dishwasher. When removing the roller ring
from cavity floor for cleaning, be sure to
replace in the proper position.
9. Remove odors from your oven by
combining a cup of water with the juice
and skin of one lemon in a deep
microwaveable bowl, microwave for 5
minutes. Wipe thoroughly and dry with a
soft cloth.
10. When it becomes necessary to replace the
oven light, please consult a dealer to have
it replaced.
11. The oven should be cleaned regularly and
any food deposits removed. Failure to
maintain the oven in a clean condition
could lead to deterioration of the surface
that could adversely affect the life of the
appliance and possibly result in a
hazardous situation.
12. Please do not dispose this appliance into
the domestic rubbish bin; it should be
disposed to the particular disposal center
provided by the municipalities.
13. When the microwave oven with grill
function is first used, it may produce
slight smoke and smell. This is a normal
phenomenon because the oven is made of
a steel plate coated with lubricating oil,
and the new oven will produce fumes and
odor generated by burning the lubricating
oil. This phenomenon will disappear after
a period of using.
